you seem aimless dear.the same happened with me a few years back.I just had to pull myself together by myself as i was a major introvert(i still am),and i didn't have anybody to whom i can't open up.My life seem wasted but i made it my point that if i don't want to live for myself i am gonna live for others to whom i am important.
I started making my mother happy by doing little things for her.I started looking at the positive things in my life,started to try to see the good side of people aroundme, started to smile a little more .!And lastly i dedicated myself to my studies and my family.And trust me it worked!
